DeepSeek V4 Flash produces corrupted output and hallucinated internal instructions
Venersiss · ghdev · 2026-08-17
A user reported that DeepSeek V4 Flash outputs corrupted text and hallucinated internal instructions (like scripts and VPN settings) even when prompted with 'hi' in OpenCode Go. An A/B test confirmed that DeepSeek V4 Pro responds normally in the same environment, isolating the issue to the V4 Flash version.
